Abstract

Method to prepare pulp is performed through reaction of polymerization of poly (para-phenylenterephalamide) in presence of poly (vinylpyrolidone)/ One forms mixed polymerization system of (para-phenylenterephalamide) that includes solvent for polymerization components and poly (vinylpyrolidon) with average viscous molecular mass not less than 100000, and in amount for achieving in polymerization system its concentration from 5 to 30 mass % of mass of polymer. After that to get reactive contact in polymerization system one adds stochiometric amounts of polymerization components of poly (para-phenylen-terephatalamide). One supports reactive contact of polymerization components during time for coming to anisotropic state of polymerization system. After that one performs separation of alloy fro polymerization system.
